This special issue of The Translator explores the field with a view to learning from the individuals and networks who take on such 'non-professional' translation and interpreting activities. It showcases the work of researchers who look into the phenomenon within a wide variety of settings: from museums to churches, crowdsourcing and media sites to Wikipedia, and scientific journals to the Social Forum. Drawing on a wide range of disciplines and models, the contributions to this volume enhance the visibility of non-professionals engaged in translating and interpreting and challenge a range of widely-held assumptions within the discipline and the profession.

This is a comprehensive edition of Maxwell's manuscript papers published virtually complete and largely for the first time. Maxwell's work was of central importance in establishing and developing the major themes of the physics of the nineteenth century: his theory of the electromagnetic field and the electromagnetic theory of light and his special place in the history of physics. His fecundity of imagination and the sophistication of his examination of the foundations of physics give particular interest and importance to his writings. Volume I: 1846-1862 documents Maxwell's education and early scientific work and his major period of scientific innovation - his first formulation of field theory, the electromagnetic theory of light and the statistical theory of gases. Important letters and manuscript drafts illuminate this fundamental early work and the volume includes his letters to friends and family, general essays and lectures and juvenilia.
